Or...just run on over to your local auto parts store and pick up a couple bucks worth of parts and run a jumper (splice) from your reverse lights down to the plug on the truck, crimp on a female connector and just hook it up when you connect the trailer. My local U-Haul shop did this for me in 10 min on my od 4Runner. No more worries during launching or any other time for that matter...good luck!
